PRO'NG-ATTACHED SLIDING-TONGUE BUCKLE.

Specification of Letters Patent. Patentd Ma 23 1915 Application filed November 21, 1912. Serial No. 732,690.

Sliding-Tongue Buckles, of which the fol-- lowing is a full, clear, and exact description.

The primary object of this invention 1s to provide a buckle, for use on knee-pants or knickerbockers, which carries its own attaching medium, so as to avoid the necessity, save the time and overcome the nsecurity of sewing now commonly practised, and will not readily fray or abrade the strap ends.

The invention is applicable to a variety of forms of buckles, but its most efiicient application is to one having a sliding tongue.

The invention consists of a buckle having a cross-bar provided on opposite edges with integral prongs which are adapted to penetrate the goods and then be clenched, these prongs being arranged staggering so that as they curl toward each other in the act of setting, their points will not conflict. The cross-bar is depressed nearly or quite to the plane of the back of the buckle so that it forms a sort of fulcrum upon which the buckle may be tilted in order to facilitate the insertion of the strap end in the buckle.

In the accompanying drawings, illustrating the invention, in the several figures of which like parts are similarly designated, Figure 1 is a top plan view; Fig. 2 is a bottom plan view, and Fig. 3 is a longitudinal section illustrating a preferred embodiment of the invention. Fig. 4 is a longitudinal section showing the buckle applied.

The frame has the side bars 1, with the introverted flanges 2 forming slideways for the sliding tongue; the end-bars 3 and 4, which are devoid of prongs or teeth that would penetrate the strap, and the intermediate, substantially central, cross-bar 5 which is depressed from the level of the face of the frame to or substantially to the level of the back of the frame. Four, more or less prongs 6 extend integrally from opposite edges of this cross-bar, backwardly, and they are arranged staggering so that when clenched on a garment their points will be out of line and not conflict one with another, but will curl over toward the center of the cross-bar and alongside one another.'

It will be understood that suitable tools or machines, having essentially a plunger or hammer and an anvil, will be used, instead of a needle and thread, to set or attach the buckle, and the comparative advantage is that the work may be done more quickly, and the fastening or attachment will be more secure. The depression of the crossbar makes of it a fulcrum upon which the buckle may be tilted in order to facilitate the insertion and removal of the strap end 7. We prefer to use with this attaching fea ture a sliding tongue 8, mounted in the slideways formed by the introverted flanges 2, and this tongue has an opening 9 for the entrance of thefree end strap 7, next to which 1s the gripping bar 10 having in its leading edge the upstanding dents 11 running out at an incline to nothing at about the middle of the bar 10 and standing up forwardly to a height sufficient to crimp the strap lengthwise and also to abut against the end bar 3 so as to restrain the tongue from escape from the frame in that direction. The depressed cross-bar 5 prevents the escape of the tonguein that direction, because said cross-bar overhangs the slideways in which the tongue moves. The leading edge 12 of the gripping bar 10 extends forward of the dents and underlies the end bar 3 so as to cooperate with the adjacent edge of said end bar to grip the strap, especially if it be thin.

As shown in Fig. 4, the buckle is attached directly by its prongs to a garment having an opening,such as the cuff of knee-pants, the parts of which are here represented at 13, and the strap end 7 is then passed up opening 9 and over the'tongue and crossbar 5 and thence under the end bar 4 of the frame. Strain placed on the strap will be resisted by the dents 11 and the gripping edges of the bars 10 and 3 and the strap end thus will be firmly held. The grip upon the strap is further promoted by the bight put in the strap by the usual finger-hold 14.

A feature of importance in connection with this buckle is that where the strap is fastened and unfastened frequently, as is the case when buckles are used upon kneepants, and any sort of penetrating buckle from the back of the buckle through thefrayed out; but with the gripping sliding tongue this sort of damage is greatly minimized it not wholly avoided.

W We claim is 1. A prong-attached buckle, comprising a frame having side bars and end bars devoid of prongs or teeth, a buckle-attaching cross-bar arranged between the end bars and connecting the side bars and depressed below the level of the face of the frame and having prongs integral with and extending backwardly from its opposite edges and out of line with one another, and it strap-gripping device at one end of the iranie.

2. A prong-attached buckle, comprising a frame having side bars and end bars devoid of prongs or teeth, a buckle-attaching crossbar arranged between the end bars and connecting the side bars and depressed below Copies of this patent may be obtained for five cents each,

Washington, 33

the level of the face of the frame and having a plurality of prongs integral with and extending backwardly from its opposite edges and out of line with one another, and a sting-gripping device arranged at one end of the frame and movable toward and from the cross-bar, said cross-bar when fastened to an article by its prongs serving as a tulcruni upon which the buckle may be tilted to facilitate the insertion of the free end of the strap into the buckle.

In testimony whereof we have hereunto set our hands this 20th day of November A. D. 1912.
